Well designed and quality construction.

This product is very well made. The suction cups work perfectly. The problem is that it takes a lot of sun to produce 3.3 watts. You will most likely see 70 to 150mA. Which is less than 2 watts. It hasn't been used much, I'm not sure there's enough power to keep a lead acid battery going forever in the winter sun.

Pros
  • Good product for the price
Cons
  • Not as thick as other picks

Disconnect the array while the engine is…

Pros
  • High scores for support and durability from testers
Cons
  • Negative gift
